- Many of the hazards in forestry are due to the handling of large trees and large machinery in rough terrain and remote areas. Activities such as maintenance and repair work have been identified as especially hazardous in the highly mechanised cut-to-length method. Accidents are underreported, which emphasises the need for a systematic approach for accident prevention. A possible procedure is the use of an analytical evaluation method to identify presumptive hazardous situations and ergonomic issues before accidents can occur. Safety-critical sectors such as nuclear power and health care have invested many resources in these types of methods. The aim of this paper is to put one of those methods to test in a forestry context in a study evaluating maintenance of forest machinery. A framework for evaluation, Combined Cognitive and Physical Evaluation, known as CCPE, was selected and adapted for the study. The evaluation was successful in systematically predicting what could happen in hazardous situations with regard to use error and ergonomic issues.

- Context. Galaxies which strongly deviate from the radio-far infrared (FIR) correlation are of great importance for studies of galaxy evolution as they may be tracing early, short-lived stages of starbursts and active galactic nuclei (AGNs). The most extreme FIR-excess galaxy NGC 1377 has long been interpreted as a young dusty starburst, but millimeter observations of CO lines revealed a powerful collimated molecular outflow which cannot be explained by star formation alone. Aims. This paper aims to determine the nature of the energy source in the nucleus of NGC 1377 and to study the driving mechanism of the collimated CO outflow. Methods. We present new radio observations of NGC 1377 at 1.5 and 10 GHz obtained with the Jansky Very Large Array (JVLA) and Chandra X-ray observations. The observations are compared to synthetic starburst models to constrain the properties of the central energy source. Results. We obtained the first detection of the cm radio continuum and X-ray emission in NGC 1377. We found that the radio emission is distributed in two components, one on the nucleus and another offset by 4?5 to the south-west. We confirm the extreme FIR-excess of the galaxy, with a qFIR ? 4.2, which deviates by more than 7? from the radio-FIR correlation. Soft X-ray emission is detected on the off-nucleus component. From the radio emission we estimated for a young (
